acctmerg(8)
NAME
acctmerg - Merges total-accounting files into an intermediary file or a
daily accounting file
SYNOPSIS
acctmerg -[ahipv] [specification] -[tu] [file ....]
FLAGS
-a [specification]
Produces output as ASCII records.
-h [specification]
Lists column headings. This flag implies -a but is effective with the
-p or -v flags.
-i [specification]
Expects input files to have ASCII records that are converted to binary
output records.
-p [specification]
Lists input but without processing.
-t Produces a single record that contains the totals of all input.
-u Summarizes by user ID rather than by user name. This is convenient when
a single user ID is allocated to more than one user name.
-v [specification]
Produces output in ASCII, with more precise notation for floating-point
values.
DESCRIPTION
The acctmerg command combines process, connect time, fee, disk usage, and
queuing (printer) total-accounting records in tacct binary or tacct ASCII
format (see the tacct structure in the acct.h file format for a description
of this total-accounting format). The acctmerg command writes the results
of record processing to standard output. The accounting file produced by
the acctmerg command may have entries for as many as 18 columns. Column
headings are printed only when you use the -h flag. The following table
lists the column headings by number, the column heading by label, and the
purpose of the entry:
1. UID User ID. This is the integer value of the user ID from the
/etc/passwd file.
2. LOGNAME
User login name. This is the alpha user login name from the
/etc/passwd file.
3. PRI_CPU
Prime-time CPU run time. This is the total time in seconds that
prime-time CPU run time was charged to the user during the active
accounting period.
4. NPRI_CPU
Nonprime-time CPU run time. This is the total time in seconds
that nonprime-time CPU run time was charged to the named user.
5. NPRI_MEM
Prime-time memory K-core. This is a measure of memory usage
during prime time. This value expresses the amount of memory used
and the elapsed amount of prime time during which it was used
(K-core is the product of total CPU time in minutes and mean size
of memory used).
6. NPRI_MEM
Nonprime-time memory K-core. This is a measure of memory usage
during nonprime time.
7. PRI_RD/WR
Prime-time read and write characters. This is the total number of
characters transferred during prime-time operation.
8. NPRI_RD/WR
Nonprime-time read and write characters. This is the total number
of characters transferred during nonprime-time operation.
9. PRI_BLKIO
Prime-time number of I/O blocks. This is the total number of I/O
blocks transferred during prime-time read and write operations.
The number of bytes in an I/O block is implementation dependent.
10. NPRI_BLKIO
Nonprime-time number of I/O blocks. This is the total number of
I/O blocks transferred during nonprime-time read and write
operations.
11. PRI_CONNECT
Prime-time connect duration. This is the total number of prime-
time seconds during which a connection existed.
12. NPRI_CONNECT
Nonprime-time connect duration. This is the total number of
nonprime-time seconds during which a connection existed.
13. DSK_BLOCKS
Disk blocks used. This is the total number of disk blocks used.
14. PRINT
Number of pages printed. This is the total number of pages queued
to any printers in the system.
15. FEES Special fee charge units. This is the number of integer units to
charge for any special fee. This value is the one supplied when
the /usr/sbin/acct/chargefee command is processed during the
active accounting period.
16. PROCESSES
Number of processes. This is the total number of processes
spawned by the user during the active accounting period.
17. SESS Number of logins. This is the total number of times the user
logged in during the active accounting period.
18. DSAMPS
Number of disk-accounting samples. This is the total number of
times during the active accounting period that the disk-
accounting command was used to get the total number of disk
blocks listed in the DSK_BLOCKS column. When the value in the
DSK_BLOCKS column is divide by this number, the average number of
disk blocks used during the accounting period is obtained.
Total accounting records are read from standard input and any additional
files (up to nine) you specify with the file parameter. File records are
merged according to identical keys, usually the user ID and user login
name. To optimize processing performance, output is written in binary,
unless the -a or -v flag is used.
Normally the acctmerg command is called from the runacct shell procedure,
either to produce an intermediate file (/var/adm/acct/nite/daytacct, for
example) when one or more source accounting files is full, or to merge
intermediate files into a cumulative total (/var/adm/acct/sum/tacct, is
another example). The cumulative total daily files are the source from
which the monacct command produces an ASCII monthly summary file, which is
written to the /var/adm/acct/fiscal subdirectory.
The optional specification parameter allows you to select input or output
column entries, as illustrated in Example 1. Field specifications are a
comma-separated string of field numbers. Field numbers are referenced in
boldface type in the first column of the foregoing list together with their
respective column headings. When you specify field numbers they should be
listed in the order specified by the boldfaced heading reference numbers.
Inclusive field ranges may also be specified, with array sizes properly
taken into account except for the ta_name number of characters. For
example, -h2-3,11,15-13,2 displays the LOGNAME (2), PRI_CPU (3),
PRI_CONNECT time (11), FEES (15), PRINT (14), DISK_BLOCKS (13), and again
LOGNAME (2), in that order, with the described column headings (-h). The
default specification is to output all 18 columns (1-18 or 1-), which
produces rather wide output records that contain all the available
accounting data.
Queuing system, disk usage, or fee data can be converted into tacct records
with the acctmerge command, using the -i flag and the specification
parameter.
EXAMPLES
1. To merge inclusive fields from an ASCII disk-accounting file called
dacct into an existing total-accounting file named tacct as binary
information, but with entries for fields 1, 2, 13, and 18 only, enter
the following line:
acctmerg -i 1 -2,13,18 <dacct | acctmerg tacct >output
The acctmerg command reads the columnar entries for UID (1), LOGNAME
(2), DSK_BLOCKS (13), and DSAMPS (18) from the dacct file as input,
merges this information as tacct binary records, and writes the result
to standard output as ASCII.
2. To repair file jan2.rpt in inclusive tacct columnar format, enter the
following initial command, edit the jan2.tmp file, and then enter the
last command:
acctmerg -v <jan2.rpt >jan2.tmp
Edit jan2.tmp as desired....
acctmerg -i >jan2.tmp >jan2.rpt
The first command redirects the content of file jan2.rpt to file
jan2.tmp, with ASCII output and floating-point values. After you edit
file jan2.tmp, the last command redirects file jan2.tmp as ASCII input
to file jan2.rpt as output, with output records in binary.
